Evaluation of a biological foliar fertilization system, in the production, agronomic and quality characteristics of three wine grape varieties


Context and purpose of the study – Evaluation of the fertility management practices in wine grape varieties production. Wine grape represents one of the most important productions in Greece with major impact to the socioeconomic characteristics of the country. The objective of this study is to evaluate, with the support of Geospatial Technologies, the potential effects of an innovative foliar fertilizer system, which is composed of three parts: a mineral fertilizer in a micronized formulation, a biostimulant as an enhancing factor of the process and, an amino acid compound (SANOVITA concept). The study was established at a collaborative, private vineyard, in the area of Trilofos-Thessaloniki, at the region of Northern Greece. The overall process will enhance the existing, cultivating practices of the vineyard, developing qualitative characteristics of the final product in order to establish a strong brand name called “Petit Oineonas”. The spraying was chosen to be made in only three French varieties (Merlot, Cabernet Sauvignon and Syrah), mainly because of an equal area size.

Material and methods – The vineyard was established at the location of Trilofos, Thessaloniki, Greece in fifteen lines in an area of almost 0.4 ha (4 stremmata). Half of the vineyard is sprayed with the system at two growth stages, while the grower applies organic management to the vineyard. The experimental design includes for each line of the fifteen corridors the following approaches: 1st part-a Control part with no application, 2nd part-an application of the SANOVITA concept (applied foliar in two growth stages during the growing season), 3rd part-a second Control part with no application and 4th part- an application of the SANOVITA concept. Data measured included NDVI, GIS (Geographic Information Systems) applications, use of Sentinel-2 satellite images, fruit size, sugar content and visible observations were recorded.

Results – Results from this year, have shown that the additional application of the foliar system based on GIS applications and spatial statistics has increased the yield and improved the overall quality of the grapes (weight, grape size and resulted in changes in sugar content). The study will be continued for additional 3 years for establishing further spatiotemporal comparison achievements.

Relation entre les caractéristiques des fromages d’Appellation d’Origine Contrôlée et les facteurs de production du lait

Les fromages d’Appellation d’Origine Contrôlée (AOC) représentent un enjeu économique important pour la filière laitière (11 % des fromages produits en France sont des fromages d’AOC, et dans certaines régions de montagne, cette proportion dépasse 50 %). Les spécificités de ces fromages et leurs liaisons avec les caractéristiques du terroir constituent un système complexe où interagissent en particulier la technologie fromagère et les caractéristiques des laits (composition chimique en particulier). Ces dernières dépendent elles-mêmes des caractéristiques des animaux (origine génétique, facteurs physiologiques, état sanitaire) et de leur mode de conduite (alimentation, hygiène, traite…) (fig. 1). L’influence de ces facteurs de production (alimentation et type d’animal en particulier) sur les caractéristiques des fromages est fréquemment mise en avant par les fromagers, sur la base d’observations empiriques. Il existe cependant très peu de travaux expérimentaux sur le sujet, en raison, entre autres, de la difficulté de séparer correctement les effets propres de ces facteurs d’amont de ceux liés à la technologie fromagère.

Measurement of grape vine growth for model evaluation

Within a research project for simulating the nitrogen turnover in vineyard soils and the nitrogen uptake by the grape vine, a previously developed plant growth model (Nendel and Kersebaum 2004) had to be evaluated. A dataset was obtained from a monitoring experiment at three vineyard sites with different soil types, conducted in the years 2003 and 2004.

Everything else, it’s work ”Socio-cultural dimensions of terroir among Bordeaux winemakers

In 2010, the OIV adopted a resolution that defines ‘terroir’. The OIV definition understands terroir as the result of the interactions between the physical specificities of a space and human labor, with an emphasis on the subsequently produced collective knowledge (OIV-VITI 333-2010); by doing so, it alludes to the social and cultural dimensions of terroir.

Is the consumer ready for innovative fruit wines?

AIM: Wine consumption in the last fifteen years showed a decrease in Europe [1]. New alternatives of wines appeared on the market. Those beverages are obtained by blending wines and fruit juices or flavoring wines with artificial or natural aromas and have medium alcohol content (from 8 to 10.5%) [2]. Recently, an innovative fruit wine has been proposed obtained by co-fermenting grape must and kiwi juice [3] whose potential attractiveness to consumers should be exploited. However, differences in product acceptability and perception, as well as the individuals’ willingness to consume and pay could change in function of subjects socio-demographic characteristics. The target group selected is represented by young adults (18-35 years old) consumption groups.

The complex response of Mediterranean viticultural systems to climate change: a case study from France and Australia

Climate change could put at risk viticultural areas situated at the hotter margins of Vitis vinifera growth climatic range. We focus on two such regions with a Mediterranean climate
